GlIl'STAF SJOLANDER, OF MIDLAND, MICHIGAN.

AUTO-R-EST.

To (ZZZ u'lzomit m on concern:

Be- 1tknown that I, GUSTAF SJOLANDER, a

' citizen of the United States,residing at Midland, in the county of Midland and 'State of Michigan, have invented new and useful Improvements in Auto-Rests, of which the following is a specification.

This invention relates to auto rests, the ob ect of the invention being to provlde a device in the nature of an attachment to an automobile, the said device remaining attached to the machine and being continually carried thereby and adapted, whenever necessary, to elevate the automobile so that the wheels will be out of contact with the floor, ground or other surface on whichthe automobile has previously been resting.

A further object of the invention is to provide a device of the character referred to which is capable of being operated by the driver without leaying his seat in the machine. I

'The invention also has for its object to providea construction of jack or rest, the

parts of, which may be drawn upwardly so as not to interfere with the operation of the machine and to provide the necessary road clearance.

\Vith the above and other objects in view, the invention consists in the construction, combination and arrangement ofparts, as

- will hereinafter be more fully described,

illustrated and claimed.

In the accompanying drawings :Figure 1 is perspective view of an automobile rest embodying'the present invention and shown detachedfrom the machine. Fig. 2 is a side elevation of an automobile showing the appliance of this invention mounted thereon.

The automobile rest contemplated inthis invention comprises essentially a bottom truck designated generally by the reference characterA and embodying a pair of spaced parallel frame bars 1 and. a centrally arranged connecting cross bar 2 rigidly fastened at its opposite ends to the bars 1 at or near the center of the latter. The bars 1 are provided at. their opposite extremities with supporting casters t while another caster is placed on the under side of the reach bar 52- just to one side of the center of the latter.

6 designates a jack screw thelower extremity of which is connected by a ball and socket joint 7 to the reach bar 2, sufficiently to one side of the center of the latter to enable said jack screw to avoid the drive shaft Specification 'of Letters Patent.

of the automobile, which drive shaft is usually located in the exact longitudinal center of the machine.

8 designates a nut through which the jack crew 6 is threaded, said nut being provided with an enlarged flange 9 to which is fastened by means of bolts 10 or their equivathrough the floor of the automobile body l and in the preferred embodiment of the invention is provided with a squared upper extremity 14 adapting it to receive and be operated by' a socket wrench 15.

16 designates coiled springs terminally connected to the truck and the frame of the automobile, said springs serving to balance the automobile after the wheels thereof have been elevated clear of the ground' These springs do not interfere with the raising of the truck A when the machine is not in use, said truck being raised to a point close up to the bottom of the automobile body so as not to interfere with the operation-of the machine on the road.

' From the foregoing description it will be seen that th'e device hereinabove described is in the nature of a combination jack, truck and lock, or in other words, the device operates to elevate the machine out of contact with the ground, it also enables the machine while supported thereby to be rolled from place to place, and it also prevents the machine from being operated by an unauthorized person as the wheels are sustained out of operative contact with the floor orground' The device will also be found beneficial in savingwear and tear on tires as it is an easy matter requiring only of the fact that the device aswa whole is 7 carried continually by the car, it is unnecessary to carry the usual jack in the tool box or under the seat. In case the machine should become mired, the wheels of the machine may be lifted clear of the ground by means of the device hereinabove described sufiiciently to place boards or the like under the wheels, thus enabling the machineto extricate itself under its own'power.

The device of thisinvention is attached to the body of the vehicle so as to bring the jack screw 6 as near as possible to the center of' gravity of the vehicle, thereby reducing as far as possible any uneven stress on the balancing springs and enabling the machine I to be supported with all of its wheels clear of the ground or floor.

- iVhat I claimv is I l. The combination with a motor driven vehicle, of a truck located beneath and carried by the body of the vehicle, a jack screw for raising andlowering said truck, said jack'serew being operable from above the floor of the vehicle, and yieldable body balancing connections between said'tr'uck and vehicle body."

The combination with a motor driven vehicle, of a truck located beneath the body of the vehicle, caster wheels adapted to support said truck, a jack screw for raising and lowering said truck, said jack screw being operable from above the floor of the ve hicle, a nut through which said jack screw is'threaded, a brace connecting said nut rigidly with the frame of the machine, and springs interposedbetween said truck and the fran'ie of the vehicle,

3. The combination with a motor driven vehicle, of a truck mounted below the body of the vehicle, a jack screw for raising and lowering said truck, said ack screw having a ball and socket connection with the truck .andbeing operable from above the floor 0f the vehicle, a nut through which said jack screw 1s threaded, a brace rlgldlysupport- 111g said nut and connected to the frame of the machine, and balancing connections be-
